ABSTRACT:
A composition and method for inhibiting white rust formation on galvanized surfaces. The composition includes hydroxyl-substituted monoamines and polyamines, imino derivatives, and hydroxyamine derivatives. The composition may be introduced onto the galvanized surface, especially in an industrial water system, using a variety of different methods or programs including integrating with current programs or developing a new program.
